NAME

defpattern − defines patterns

SPECIFICATION

C
defpattern(n, size, mask)
short n, size;
short *mask;

FORTRAN
subroutine defpat(n, size, mask)
integer*4 n, size
integer*2 mask((size*size)/16)

Pascal
procedure defpattern(n, size: Short; var mask: Short;

DESCRIPTION

defpattern defines an arbitrary pattern.  n specifies an index into a table of patterns.  size specifies the size of the pattern: 16, 32, or 64 for a 16x16-, 32x32-, or 64x64-bit pattern, respectively.  mask is an array of shorts that form the actual bit pattern.  The pattern is described from left to right and bottom to top, just as characters are described in a raster font.  By default, pattern 0 is a 16x16 solid pattern that cannot be changed.  There is no performance penalty for non-solid patterns. 

When using multiple windows, patterns, cursors, and fonts are available to all windows.
